36              LIS_SCALE_JACOBI
37                     Jacobi scaling D^-1 A x = D^-1 b, where D represents  the
38                     diagonal of A=(a_ij)
39
40              LIS_SCALE_SYMM_DIAG
41                     Diagonal  scaling  D^-1/2  A  D^-1/2  x = D^-1/2 b, where
42                     D^-1/2 represents the diagonal matrix with (a_ii)^-1/2 as
43                     the diagonal
